Does liver have GLUT 4?
C Role of the Liver The glucose transporter system (GLUT-4) across the membrane is rate limiting in peripheral tissues that are sensitive to insulin (muscle, fat). At a blood glucose level of approximately 8.33 mmol/l (150 mg/dl), the liver does not take up or supply glucose to the circulation.Click to see full answer. Also know,…

Also know, where is GLUT 4 located?GLUT4 is the insulin-regulated glucose transporter found primarily in adipose tissues and striated muscle (skeletal and cardiac).One may also ask, what is the difference between GLUT 2 and GLUT 4? GLUT2 is insulin independent (Liver and pancreas), GLUT4 is insulin dependent (on muscle, adipose, heart). GLUT2 has a higher Km and so transport is not maximally active at low concentrations. Postprandially when blood glucose is higher than the km transport into liver and pancreas will be high. Subsequently, question is, what is the purpose of GLUT 4? Skeletal muscle both stores glucose as glycogen and oxidizes it to produce energy following the transport step. The principal glucose transporter protein that mediates this uptake is GLUT4, which plays a key role in regulating whole body glucose homeostasis.Which glut is insulin dependent?GLUT4 is insulin-dependent and is responsible for the majority of glucose transport into muscle and adipose cells in anabolic conditions.
